Spatial Solitons in 2D Lattices

Gaetano Assanto, Katia Gallo, Alessia Pasquazi and Salvatore Stivala

These authors describe their observation of two-color optical solitons in a 2D parametric photonic lattice with hexagonal symmetry in lithium niobate. Their results have enabled wavelength-controlled angular steering and transverse displacement of self-trapped filaments of light.
